When did invites go out for your showers?

I'm having 2 showers, one for each side of the family, but neither group has sent out invites yet! I'm getting a little nervous because the showers are the 1st and 2ns weekend of March....but I don't want to nag the people hosting because then I'll seem ungrateful. It's stressing me out so much! 😳
